46 Claims. vMC1. 122-52) This invention relates to a machine foroperating on shoe parts and as illustrated herein is more particularlyrelated to a machine for adhesively uniting tongues and linings.

A machine for assembling tongues and linings is shown and described inUnited States Letters Patent No. 2,272,207, granted February 10, 1942,on an application filed in the name of Adrien L. Jalbert. In thatmachine the tongue and lining are placed on reciprocating tables whichmove the pieces toward two pairs of feed rolls, one of the rolls beingsupplied with cement, thereby to apply cement to one side of the tongue,and two of the rolls co-operating to press the tongue and lining intoengagement. It is an object of this invention to provide an improvedmachine of that type having increased speed and accuracy of operationand at the same time requiring less skill to operate the machine.

In the improved machine, stationary work tables are provided to hold thecomponent parts oi the work prior to their presentation to the adhesiveapplying and uniting rolls, and reciprocating work clamps are employedfor moving the component parts of the work along the tables toward theapplying and uniting rolls. In order to position the parts of the workonthe tables so that they will be in proper registration when pressed faceto face by the uniting rolls, gages against which the operator placesthe work pieces are associated with the tables, and one feature of theinvention resides in an arrangement of this sort having novel means forwithdrawing the gages from the tables to permit movement of the workalong the tables toward the uniting rolls without interference prior tothe movement of the Work clamps.

The uniting rolls for pressing the tongue and lining together areindependently driven and, in order to permit the passage ofirregularities in the Work, they are mounted for movement relative toeach other. In order to provide for this relative movement, and yet toretain direct drive, Oldham coupings are employed. As a result, when oneroll is moved laterally because of a high spot in the leather, it slidessidewise in the Oldham coupling, thereby varying the speed of the rollslightly. As a consequence, one roll will move faster or slower than theother and the pieces of Work may be displaced with respect to each otheror wrinkles may be formed in the work. To prevent this, there isprovided, in accordance with another feature of the invention, meanswhereby movement of one of the rolls bodily because of a-high spot or abump in the work will produce an equal movement of the other roll bodilyso that both rolls occupy corresponding positions with respect to theirOldham couplings, thereby causing the uniting rolls to always rotate atthe same peripheral speed relative to each other.

It is desirable to collect the assembled tongues in a work holder and tomold them during the time when the cement is setting and drying. Withthis in mind, another feature of the inven tion resides in` Worktransferring or stacking mechanism arranged to transfer the assembledpieces from the uniting rolls to the work holder. To accomplish themolding, the work holder comprises a forming plate and means forretaining the work in engagement with the forming plate so that when theassembled tongues are disposed in the work holder between the formingplate and the retainer they will be bent transversely to a contourcorresponding substantially in shape to the instep of the foot.

The inventionwill now be described in detail with reference to theaccompanying drawings, in which Fig. 1 is a front elevation of theentire machine;

The machine as illustrated herein comprises generally a pair of worktables l and l2 (Fig. 1) upon which the two component parts of the linedtongue may be placed at opposite sides of the machine, a pair of'workfeeding means I4 and I8 arranged to move the parts inwardly along thetables to a pair of work uniting rolls i8 and 20, means for applying anadhesive to the lower surface of one of the parts of the work, indicatedgenerally by the reference character 22 (Fig. 4), and work transferringor stacking mechanism 24 (Fig. l) for removing the assembled tongue andlining from the uniting rolls and depositing it in a work holder andformer 215 (Fig. 16) in stack form so that a number of lined tongues maybe accumulated and removed from the machine at one time. The elements ofthe machine referred to above are assembled in co-operating relationupon a frame 28 which, in turn, is supported on a base 38 (Fig. 1).

The work supporting tables l and l2 provide so positioning the tongueand lining that when other.

they are pressed into engagement they will be united in the properrelation with respect to each Since lthe work is moved along the surfaceof the tables, the gages 45 and 48 must be withdrawn from the surfacesof the tables during the forward feeding movement of the work and,consequently, the gages are mounted on reciprocable arms 52 (Fig. 2)which are positioned below the tables on opposite sides of the machineand which are operable to withdraw the gages immediately prior to theactuation of the feeding means so that they will not impede the progressof the work. The arms 52 are adjustably mounted at their rear ends onthe opposite ends of a shaft 54 journaled in the frame 28 (Fig. 2) andare fixed to turn with the shaft by means of clamps 5B fixed thereto byscrews 58. Pairs of screws 60 and 62 are carried by the clamps 56 andabut opposite sides of the arms 52, thereby providing means foradjusting the position 'of the arms with respect to the shaft 54 andconsequently affording means for adjusting the height to which the gagesand 48 will project above the surfaces of the tables.

'Ihe gages 48 and 48 are provided along the front sides and inner endsof the tables (Fig. 8) and are adjustably mounted on the arms 52 inorder to accommodate work pieces of different sizes and also to permitpositioning one part with respect to the other. To this end, the freeends of the arms 52 are recessed, providing smooth surfaces 64, =asshown in Figs. 9 and 14, leaving shoulders 66. The side gages 4B areprovided with H-shaped bases 88 (Fig. 11) which rest upon the surfaces84 and are heldin spaced relation by means of spacers 10 and 12,the'former being v U-shaped. Cover 'plates 'I4 having slots 'I8 forhorizontal surfaces upon which the operator may place the parts of thework. Vertical skirt portions 32 depend from the front edge of thetables. The lower edge of the skirt at the left side of the machinemeets the top edge of a 'wall 34 e'xtending vertically from the base 30along the front of the machine. At the right side ofthe machine (Fig. 1)the wall 34 is cutaway along the line S8 and a'panel 38 is set thereinwith Vits upper edge meeting the lower edge of the Vskirtv dependingfrom the table I8,`for 'a purpose which will appear hereinafter. V"riretables loana 12 are of thegage pins. t y of end 'plates 86 (Fig. 11)disposed between the the passage of 'the ends of the gage pins -areplaced over the H-shaped bases of the gagesand are fastened to thesurfaces 84 by means of screws 'I6'. Notches 18 are formed at the edgesof the cover plate into which project the ends of the U-shaped spacers10, a few thousandths clearance being provided to permit adjustment, aswill appear hereinafter. The spacers 12 are held in place by means of apair of pins 88 which project through holes 82 formed in the coverplates '54, the holes being a few thousandths oversize to permitadjustment, as will appear hereinafter. The cover plates 14 'are held bymeans of washers 84 placed between the 'surfaces 84 and the cover plates1'4 slightly -above the top surfaces of the H-shaped bases 68 so thatthere is suicient clearance to permit the gages to be moved widthwise ofthe surfaces V(i4. Thus, it is apparent that the bases 'of theV gagepins may be slid between the surfaces 64 and the cover plates 14. Inorder to lock the side gage pins in place after-they have been set inthe proper position, means is provided for forcing the spacer plates 78and 12 against the I-ll-shaped bases' This isaccorn-plished by meanscover plates 14 and the surfaces 64 with their inner edges adjacent tothe bases of the first of the gage pins. Reduced extensions 86 areformed on the outer ends of the end plates 86, the extensions havingdownwardly projecting flanges 98 through which bolts 92 are passed. Theinner ends of the bolts 92 are threaded into the arms 52 and are lockedin position by means of nuts 94. Knurled thumb nuts 96 are placed on theouter ends of the screws and by rotating the-screws in a right-handeddirection the end plates 86 may be forced inwardly, as seen in Fig. 11,thereby` taking up the slack between the spacer plates 18 and 12 and thebases of the gage pins so as to lock them securely in place. The gages48 and 48 at the inner ends of the tables, as heretofore indicated,locate the component parts of the work so that when they are united thetongue will overlap the lining a proper amount at its end. The gages 48for the leather or exposed` part of the tongue, which is disposed on theright-hand table, as shown in Fig. 1, are fixed. The gages 48 on theleft-hand table for the lining, however, are adjustable so that thelongitudinal position of the liningmay be adjusted to give the propermargin of overlap. The means for adjusting these gages 48" is shown inFig. 9. The gages 48', which are two in number, are fastened to a block98 slidably mounted on a bifurcated extension formed integral with theinner edge of the left-hand arm 52 and extend upwardly through a pair ofslots |82 formed in the table |2. A screw |04 is journaled in bosses |06formed on the under side of the arm 52, the inner end of the screw beingthreaded through the block 98 so that rotation of the screw moves thegage pins 48 longitudinally. To prevent longitudinal movement of thescrew itself and to prevent damage to the gage pins 48 by jamming thepins against the inner ends of the slots |02, the screw |04 is yieldablyheld by means of a coil spring |08 disposed upon it between the boss |06and a collar |I0 fixed to the screw.

The gaging mechanism, except for the adjustable gages 48 just described,is identical on opposite sides of the machine and is moved into and outof work gaging position by the armsA 52, the latter being oscillated bymeans of an arm ||2 (Figs. 2 and 21) fastened to the shaft 54 to whichthe arms 52 are fixed. The arm ||2 carries a cam follower ||4 at itsupper end which rides in a cam groove ||6 formed in the peripheralsurface of a cam 8 which, in turn, is fixed tov a cam shaft |20. n

'I'he work feeding means I4 and I6 which move the work along thesurfaces of the tables |0 and I2 comprise work clamps |22 (Fig. 12).Since the work clamps are identical on opposite sides of the machine,only that at the right side of the machine has been illustrated indetail. Each work clamp consists of an unyielding jaw |24 and amovablejaw |26. .The unyielding jaw |24 (Figs. 12 and 13) is mounted onthe under side of the table l0 with its upper end extending through aslot |28 formed longitudinally of the table. In order to permit movementof the lower jaw |24 longitudinally of the table, the jaw is slidablymounted on a shaft |30 (Fig. 11) supported in a pair of shaft hangers|32 and |34, the hangers being attached to the under side of the tableby means of screws |36. The shaft |30 is prevented from turning in itshangers by means of a setscrew |38`threaded through the hanger |34. Thehanger |34, is providedwith a lateral extension |40` having formed atits front edge a groove |42 which slidably receives a tongue |44,(Fig.13) formed on the inside Aedge of the fixed jaw 24, thereby rigidly tohold the jaw |24 with its upper end on a level with the surface of thetable |0. Spaced ears |46, on the rear of the fixed jaw |24, provide anupright groove for a purpose which will subsequently appear. The movableupper jaw` |26 is attached to a bracket |48 by means of screws |50, thebracket being tiltably mounted on a stub shaft |52 which is fixed to acarriage |54 by means of a screw |56. A bolt |58 is passed through aboss |60 formed on the bracket |48 and a boss |62formed on the carriage|54, serving to hold the bracket |48fagainst a spring |64 disposedbetween the bosses |60 and |62. This permits the upper jaw |26 to yieldwhen it is brought down into engagement with thel lower jaw |24, shouldthere be any unusually thick object between the two, without damage tothe jaws.` To permit longi-A tudinal movement of the upper jaw, thecarriage |54 is slidably mounted on a shaft |66 (Fig. 11) which, inturn, is supported on the arm 52 by means of bosses |68 and |10. A pin|12 is passed through the shaft |66 in the bearing |12 rigidly to holdthe shaft in place. The carriage |54 is provided at one end with a.lateral extension |14 which is provided with a passage |16 for thereception of a spindle |18 fixed at its ends to the arm 52 uponpedestals |80 and |82. This permits movement of the carriage |54longitudinally of the shaft |66 and at the same time prevents it fromtipping about the shaft |66, as a center, thereby holding the upper jaw|26 in a horizontal plane. A cup |84 is formed on the back of thecarriage |54 for the accommodation of the head of a crank pin |86 fixedtherein (Fig. 11). A crank |88 is fastened to the crank pin 86 andprovides means for reciprocating the carriage 54 so as to move the upperjaw |26 longitudinally of the table. The crank |88 is fastened forreciprocation to one end of a shaft |90 (Figs. 1 and 28) journaled inthe frame 28 of the machine, the opposite end of the shaft |90 havingxed thereto a link |92, the latter being connected to a cam bar |94. Thecam bar |94 is provided with a cam follower 86 (Fig. 28) which rides ina cam groove |98 formed on one face ofthe cam 8. The opposite end of thecam bar is likewise connected by means of a link |92, a shaft |90 and acrank |88 to the lefthand work clamp, as shown in Fig. 1. It is apparentfrom the foregoing construction that as the gages 46 and 48, 48 aremoved downwardly to a level below the surface of the table the upper jaw|26 which is mounted Von the arm 52 is brought down to co-operate withthe lower jaw |24 in gripping the work. As the upper jaw is lowered intogripping position, an upright rib 202 (Fig. 13) formed thereon passesinto the groove between the ears |46. Consequently, when the upper jawis moved longitudinally of the table, it will carry the lower jaw alongwith it by means of the| aforesaid connection.

As the work is moved toward the uniting rolls |8 and 20, the leadingends thereof are caught between the lower surfaces of the rolls I8 and20 and co-operating rolls 204 and 206 (Fig. 4) which grip the leadingends and feed them inwardly against a triangular guide 268 havingconcave surfaces 2|0 which conform to the upgoing sides of the rolls I8and 20, respectively,y thereby directing the work pieces upwardly incontact with the surfaces of the rolls I8 and 20 and into contact witheach other. The Aguide208 (Fig. 1)

is supported at its ends by plates 2I2 fastened thereto by screws 2I4,the plates restingin U- shaped bearings 2I6 screwed to the frame 28. Thebase of the triangular guide 208 (Fig. 4) lies between the rolls 204 and206i and the apex extends upwardly between the rolls I8 and 20 to apoint somewhat short of a horizontalN line passing through the centersof the rolls. The concave surfaces of this triangular guide are groovedto reduce the surface of contact between the work and the guide as thework is moved along so that the adhesive applied to the surface of thework, as will appear hereinafter, will not adhere thereto. The rolls 204and 206 are mounted on parallel shafts 2I8 and 220 below the rolls I8and 20. The shafts 2I8 and 220 extend through the frame of the machineand have fixed thereto gears 222 and 224 (Fig. 26) which mesh with apair of meshing gears 226 fastened to a pair of parallel shafts 228.

The work is not always uniform in thickness and therefore it isnecessary to provide some play between the roll I8 and the surfaces ofthe roll 204 and guide 208 and, correspondingly, between the roll 20 andthe roll 206 and guide 208. It is also necessary to provide some playbetween the co-operating surfaces of the rolls I8 and 20. In order todrive the rolls and at the same time preserve the flexibility referredto, the rolls are mounted on shafts 230 (Fig. 4) which are connected bymeans of Oldham couplings 232 (Fig. 2) to the pair of parallel shafts228 (Fig. 26), One of the shafts 228 has fixed thereto a worm gear 234which is rotated by a worm 238 fastened to a driven shaft 238 (Fig. 2).The other of the shafts 228 is driven from the first-named shaft bymeans of the aforesaid meshing gears 226 fixed to the shafts 228.

While the Oldham couplings permit the rolls I8 and 20 to move relativeto each other as desired, the surface speed of the rolls will change lrelative to eachother, due to the fact that the shafts will frequentlyoccupy different` positions in their respective Oldham couplingconnection. A difference in the surface speeds of the two rolls tends tomove the tongue andv lining with respect to each other and therebydislocate their original positioning so that the tongue and lining wouldwrinkle or would not have their proper overlapping relation. To permitmovement of the rolls and at the same time eliminate any change in speedbetween the surfaces of the rolls, the rolls are mountedv as follows. Abracket 240 (Figs. 2 and 4) is Vfastened to the frame of the machine andis provided with a horizontal arm 242 which extends laterally from theface of the frame. The arm 242 has formed integral therewith a pair ofparallel spaced plates 244 which extend at right angles to the arm andare provided at opposite ends with pairs of Vbearings 246 and 248adapted to receive spindles 250 and 252. The spindles 250 and 252tiltably support pairs of arms 254 (Fig. 4), each pair being joined bymeans of avcrossbar 255. The upper end of one of the arms 254, at theleft as seen in Fig. 4, is extended at 258, the-extension being joinedby means of links 260 and 262 tothe spindle 252. The link 260 isattached at one end to the extension by means of a pin 264 and at theother end to one end of the link 262 by a pin 286. The link 262 isrigidly connected at its opposite end to the shaft 252, so that lateralmovement, for example, of theV roll 20 to thelleft (Fig. 4) will turnthe -arrn 254 in a clockwise direction. This, in turn, thrusts the link260 downwardly in the direction of its length to turn the link 262 in acounterclockwise direction. Counterclockwise movement of the shaft 252tips the arm 254 which supports the roll I8 outward in a lateraldirection opposite to the movement of the roll 20. It isapparent,therefore, that movement of either roll I8 or 20 in a lateral directionwill cause the other roll to move an equal amount in the oppositedirection. A threaded boss 268 is formed on the end of one of theright-hand arms 254 and is yieldably joined to the extension 258 byvmeans of arbolt 210 which is passed through a boss 2'I2 formed at theend of the extension 258. A coil spring 214 is placed on the bolt 210and yieldably holds the linkage in an expanded position so that ltherolls I8 and 20 are normally yieldably urged toward each other to pressthe component parts of the work together. A pair of nuts 2'I6 areprovided at the end of the bolt 210 for adjusting the proximity of therolls with respect to each other. The lower ends of the arms 254 areprovided with bosses 218 in which thereV are fixed trunnions 280, thelatter tiltably supporting pairs of angular arms 282 having at theirlower ends bearings 284 and bearing caps 266 which rotatably receive theshafts 230 to which the rolls I8 and 20 are fixed. Each pair of angulararms 282 is joined by a web 290, the webs being yieldably fastened tothe crossbars 256 (Fig. 4) by means of screws 292 and springs 294disposed between the heads of the screws and the bottoms of recessesformed in the Webs 290. The springs 294 serve yieldably to urge therolls I8 and 20 toward their co-operating rolls 204 and 2x06,respectively. Adjusting screws 256 are also provided in the webs 290which abut the surfaces of the crossbars 256 and provide means forvarying the proximity of the rolls I8 and 20 to their Acooperating rolls204 and 206.

In order to unite the tongue and lining, an adhesive is applied to theunder or flesh surface of the tongue and this is accomplished by meansof the roll 204 which constitutes an adhesive applying roll. Theadhesive applying roll 204 is supplied with adhesive by means of apick-up roll 298 (Fig. 4) which is provided with hubs 300 and trunnions302 and 304 journaled in bearings 306 carried by plates 308 attached tothe opposite walls 3 I 0 of a cement tray 3I2 by means of screws 3I4.The plates 308 have U-shaped notches in their upper edges which receivesimilarly shaped bearing blocks 3I6 in which the bearings` 306 arefixed. In order that the pickup roll 298 may be removed for cleaningpurposes and so that it may be shifted to and from the applying vroll204 to regulate 'the thickness of the adhesive on the roll 204, itstrunnion 304, which is extended (Fig. 6), is detachably connected by apin coupling 3I8 (Fig. 2) to a shaft 320.V The shaft 320 (Fig. 26) hasfixedV thereto a gear 322 which `meshes with a gear 324 fixed to theshaft 220, the latter being driven from the shaft 228 by way of thegears 226 and :224.

The cement tray 3I2 is removably supported on the base of thema'chine sothat it may be cleaned. A pair of Yguides 328, shown in Fig. 2, engageVthe opposite sides of the tray and hold it in proper alinement. The trayis yieldably locked in working position with the pick-up roll `2 98substantially in contact with the applying roll 204 by means of a hook330 which holds one end of the tray against an abutment332. The hookengages the lower edge of aplate 334 fastened' to the tray by means ofscrews 336 (Fig. 4). The hook is mounted on an arm 338 fixed to aspindle 348, the hook being held in a retracted position by means of aspring 342 fastened at one end to the arm 338 and at its opposite end tothe frame of the machine at 344. A block 346 supports the head of thehook 338 in its locked position. When it is desirable to remove thetray, the hook is moved longitudinally against the action of the spring342 until the head clears the edge of the block 346, whereupon it dropsbelow the edge of the plate 834. The tray SI2 is then movedlongitudinally beyond the head of the hook and is then withdrawnlaterally from the machine. In order to regulate the thickness of theadhesive on the applying roll 284, means is provided for shifting thetray 3I2 while it is in its locked position. To this end, the abutment332 is mounted between a pair of upright arms 348 (Fig. '1) upon a pin358 journaled in the upper ends of these arms, the arms, in turn, beingfastened to a shaft 352 by means of a pin 354. The abutment 332 issickle-shaped (Fig. 4) so that its rear end eX- tends rearwardly of thepin 358 and downwardly to a point opposite the lower end of the uprightarms 348. A screw 356 is passed through the lower end of the abutment332 and is threaded into the lower end of the arms 348, a spring 358being disposed between the abutment and the lower end of the arm. Byturning the screw 358, fthe abutment may be retracted or extended tomove the roll 288 to or from the roll 284. A lever 388 is fastened tothe outer end of the spinc lle 348 on the outside Aof the panel 38 0fthe machine and provides means for rotating the spindle 348 and therebymoving the hook 338 out of engagement with the edge of the plate 334, Apointer 362 is fixed to the outer end of the shaft 352 and co-operateswith a graduated scale on a plate 384 xed to the panel 38 to indicatethe position of the roll 288 with respect to the roll 284. The rear endof the adhesive tray SI2 is reduced in cross section at 366 (Figs. 2 and4) and terminates in a cup 368 adapted to receive the neck of anadhesive bottle arranged as a supply of the chicken-feed type. A web 318is formed integral with the reduced portion of the receptacle 3I2 and atright angles thereto, the outer end of the web providing a support towhich the panel 38 is fastened by means of screws 312. Consequently, thetray may be removed without removing the whole of the table I8.

Unless a suitable mechanism is provided, the work delivered by the rollsI8 and 28 will be piled indiscriminately, making it necessary for theoperator to reh-andle it in order to stack it and deliver it vfor itsfurther use. In the present machine, in order to eliminate unnecessaryhandiing, there is provided a work transferring or stacking mechanismand work holder, indicated generally by the reference characters 24 and26 (Figs. and 16) which is arranged also to shape the work, that is, tomoldA it to a concavty substantially complemental to the shape of theinstep. rihe work transferring device 314 is adapted to grasp theleading edge of an assembled tongue and lining as it leaves the unitingrolls and carry it upward to deposit it in a variable capacity workholder consisting of a work forming plate 818 and a retainer bar 318.The work transferring device 314 consists of an unyielding forked jaw388 and a movable forked jaw 382 which co-operates with the unyieldingjaw to grip the leading edge of the work, aslwill appear hereinafter andas shown in Fig. 20. The movable jaw 382 has formed integral therewithva sleeve 384 which is slipped over the end of a stud 386 pivotallyattached to the unyieldable jaw by means of a pin 388 (Fig. 17), theformer being loosely fastened to the stud by means of a screw 398 havinga pin 398 on its inner end which lits loosely into a diametrical holeformed inthe stud. This permits self-adjustment of the jaw 382 inaccordance with any variation in the thickness of the work. The movablejaw 382 is yieldably held in engagement with the unyielding jaw by meansof a spring 382 disposed between a web 394 formed on the unyielding jawand a perforated flange' 398 on the hub of the stud 388. The spring 382is held in place by a pin 398 passing therethrough, one end of the pinbeing fastened to the web 394 and the other end extending through theperforated flange 396. The transferring means, which consists of thejaws 388 and 382 for reciprocation between the uniting rolls and thework holder, is fastened to a carriage 488 by means of screws 399, thecarriage being slidably mounted on a vertically extending track 482(Fig. 15). The track 48-2 is formed integral with a carriage 484 which,in turn, is slidably mounted on a horizontally disposed track 488 (Figs.2 and 23), for a purpose which will appear hereinafter. The carriage 488is provided with a dovetail way (Fig. 22) which co-operates with adovetail formed on the track 482 and is slidably connected thereto bymeans of a gib 488' disposed between one side of the way and the dovetaland held in place by means vof setscrews 4|8. The carriage 484 isconnected to the track 486 (Fig. 23) in a similarv manner by means of agib 4I 2 and setscrews 4I4. When the carriage 488 is in its lowermostposition (Fig. 15) which is the position in which the jaws 3,88 and 382are ready to grasp the leading edge of the work, the movable jaw 382 isheld open against the action of the, spring 382 by means of an abutmentblock 4I6 Xed lto the lower end of the track 482 (Fig. 1.5), theblocklying in the path of a head 4 I 8 formed at the end of the flange 396and consequently'tilting the jaw 382 about its pivot 388 as the carriage488 moves to its lowermost position. The carriage 488, and consequentlythe transferring means 31.4, is reciprocated vertically, to liftsuccessive pieces of work to the work holder, by means of an arm 428(Fig. 15) which'is slidably connected to a sleeve 422'pivotally attachedat 424 to the carriage. The arm 428 at its opposite end is clamped toashaft 426 (Fig. 1) journaled in the frameV of the machine, the shaftbeing oscillated by a lever 428'the free end of which has a block 438slidable in a slot 432 formed in the end of a cam lever 434 pivoted onthe frame of the machine at 438. The lever 434 has fixed thereto a camfollower 438 (Fig. 29) which co-operates with a cam groove 448 formed inone face of a cam 442 rotation of which oscillates the lever 434 andhence the carriage 488. In order to separate the forming plate 318 andretainer bar 318 to admit the work, the carriage 488 is reciprocatedhorizontally, during its vertical movement, on the track 486 so that thetransferring means will push the forming plate 316 back from the bar318, as will appear hereinafter, by means of a lever 448 (Figs. 1 and15) pivotally attached at 448 to a flange 458 formed integral with thecarriage 484. The lever 446 (Fig. 1) is Xed to a shaft 452 journaled inthe Y frame of the machine, the shaft beingoscillated by means of alever 454 fixed thereto, the other end of the lever 454 Carrying a camfollower 456 (Fig. 30) which co-operates with a cam track 458 formed inthe opposite face of the cam 442.

The vertically reciprocating carriage 480 and transferring means 314-move the work from the uniting rolls upwardly toward the bottom of theforming plate 816. The upperportion of the transferring means 314 isU-shaped in cross section, as shown in Fig. 22, and as the carriage 400moves upwardly the beveled ends 460 of the U- shap'ed portion areparallel to the inner faces of the forming plate 316. At approximatelyonefth of the ascending stroke, that is, substantially at the pointwhere the leading edge of the tonguereaches the lower edge of theforming plate' (Fig. 19), the carriage 404 begins to move to the left,causing the vU-shaped portion 460 to straddle the retainer bar, as seenin Fig. 20, and forcing the forming plate 816 to move away from theretainer bar 318 to admit the work as it is drawn up between the plateand the bar. The combined vertical and-horizontal movements of thetransferring means cause the'transferring means to move obliquely upfrom the uniting rolls toward the work holder.

The forming plate 316 is concave or V-shaped and is fastened by means ofscrews 462 to C- shaped supports 464 depending from a bar 466 (Figs. and24) The bar 486 forms part of a frame 468 (Fig. 15) which is slidablymounted on a pair of parallel horizontally disposed rods 410. The rods410 are fixed at their ends in a pair of bosses 412 (Fig. 24) which arerigidly joined by a yoke-shaped member 414, the bracket formed therebybeing fastened to the frame of the machine by means of a neck 416. Theretainer bar 318Y is disposed opposite to the forming plate and is fixedin a vertical position to a nub extending from the yokeshaped member 414by-means of a'screw 418. The forming plate 316 is yieldably held inco-operating relation with the retainer bar 318 by means of a spring 480disposed between the bar 466 and a crossbar 482 (Fig. 25), the springbeing retained in place by studs 484 and 485. The crossbar 482 is alsoslidably mounted on the parallel rods 410 between the bars 466 of theframe 468. During the disposition of the first few pieces of workbetween the forming plate and the retainer bar, the spring 488 yields sothat the pieces are held under pressure, thereby causing them to conformtol the curvature of the forming plate. However, as the number of piecesincreases, the capacity of the holder Vmust be increasedcorrespondingly. Consequently, the frame 468 must move backwardly alongthe parallel rods 418. This movement is procured automatically as thepressure between the forming plate 816 and the retainer bar 318increases or reaches a predetermined pressure by means of a frictionplate i represented in Fig. 1.

of the spring 488 so that the frame 468 will move back only under agreat deal of pressure or under a very light pressure. The ends of therods 318 are joined by a cross member (not shown) which reinforces thewhole unit and provides a stop vfor the movement of the frame 468. Whenthe number of pieces of Work stacked between the forming plate 316 andthe retainer bar 318 has forced the frame 468 to its limiting point, astring may be tied about the lower ends of the work and the whole stackremoved from the machine.

Near the top of the vertical movement of the transferring means theleading edge of the Work abuts a surface 502 (Figs. 16 and 18) on thebottom side of the yoke-shaped member 414 which, together with thefriction between the retainer bar 818 and the forming plate 816, createssufficient drag on the work to cause further vertical movement of thetransferring means 314 to disengage the jaws from the work. Afterdisengagement from the work, the transferring means begins to move tothe right, completing its movement to the right at the upper extremityof its vertical movement, whereupon it descends to its original positionfor a subsequent piece of work. To insure an even disposition of thework pieces, a bar 504 is fastened to the frame of the machine by meansof screws 506 and 508 below the rods 410 and parallel thereto to. engagethe notched lower ends of the work pieces and to support the same, asillustrated in Figs. 1 and 16.

The driveshaft 238 is provided at its outer end with freely turning andfixed pulleys 510 and 512, respectively, a belt shifter 5I4 beingprovided for shifting the belt from one to the other of the pulleys,thereby to connect or disconnect the shaft to an outside source ofpower.

By reference to the cams shown in Figs. 27, 28, 29, 30 and the cam chartFig. 31, the sequence of operations of the machine may be followed. Theletters appearing on the cam chart (Fig. 31) correspond to similarlymarked sections of the cams whose motion is plotted on the cam chart.Referringl to the motion of the work clamps and starting for convenienceat 0 of rotation of the cam H8 at the left-hand end of Fig. 31, the workclamps are shown to be dwelling at the outer end of their stroke asDuring this period of dwell the operator is given an opportunity toplace the work on the tables. When the cam H8 has turned approximately22 from 0, the

work clamps start to move inwardly, this point being marked A in Figs.28 and 31., Inward which holds the crossbar 482 from freely slidingv onthe rods 310. This friction plate consists of a spring steel leaf 488the ends of which bear against the parallel rods 410, the leaf beingsecured to the crossbar 482 by means of a thumbscrew 480 (Fig. 25). Asthe pieces pile up between the forming plate 316 and the retainer bar318, the frame 468 moves backwardly against pressure of the spring 480until it comes in contact with the crossbar 482, or until the pressurenecessary to compress the spring 488 overcomes the frictional resistanceof the leaf spring 488, whereupon the crossbar 482 will be forced backstep 'by step. The amount of molding may be adjusted by increasing ordecreasing the action' movement of the work clamps continues until thecam has turned approximately marked B, this part of the movement servingto present the leading edges of the work to the uniting rolls. For thenext 210 of rotation, that is, to the point C, the work clamps arereturning to their outer position; and from C to A, an angular rotationof the work clamps dwell, thus completing the cycle. During thismovement the gages for positioning the work (Figs. 27 and 31) move upinto and down out of position. Starting at 0 again, the gages 46, 48 and48 are shown as being withdrawn below the tables by rotation of the camIIB so that at D, which corresponds to the initial inward movement ofthe work clamps, the gages are below the tables, thereby permitting thework clamps to move the work pieces 'along the tables withoutinterference, the cam H8 turning through approximately 60 during thistime, represented from D to E. Just prior to the completion of theinward movement of the work clamps, the cam H8 begins to return thegages toward gaging position, indicated at E, and continues to move themtoward the gaging position which is complete at the point F inapproximately 86 of rotation of the cam. For the next 192 of rotation, Fto G, the gages' remain in gaging position which coincides with thereturn of the work clamps and part of the dwell of the work clamps. At360 the gages start down and are withdrawn during rotation of the camthrough approximately 22, denoted at G-D. The cam for producing thevertical and horizontal movement of the work transferring means is shownin Figs. 29 and 30. In Fig. 31, starting at the cam 442 has moved theWork transferring means almost to the top of its stroke which occurs atH just prior to the beginning of the inward movement of the work clamps.From H to I, an angular rotation of approximately 91, the cam causes thetransferring means to descend toward the uniting rolls where it dwellsfor approximately 7 of rotation, denoted I-J. This dwell provides timefor the leading end of the work which has emerged from the uniting rollsto enter the jaws of the transferring means 314 (Fig. Beginning at J,the transferring means ascends from J to H through approximately 262 ofrotation of the cam. During the descent of the transferringv means, itsdwell, and a part of its ascent, the jaws of the transferring meansoccupy the position shown in Fig. 15 where it is just beginning itshorizontal movement O-L to the left. At the point marked L (Fig. 30)during the ascent of the transferring means, which occurs atapproximately one-fifth of its upward movement, the cam 442 begins tomove the transferring means to the left and completes this movementduring the next of rotation, thereby forcing the forming plate away fromthe retainer bar to admit the work, the forked portion 460 at this timeholding the work against the forming plate. The transferring meansremains in its extreme left-hand position, as illustrated in Fig. 19,from M to N, a cam rotation of 114, and then begins to return to theright near the top of its ascent. This allows the forming plate toreturn toward the retainer bar and grip the work so that further upwardmovement of the transferring means slips the jaws from the end of thework. The completion of the movement of the right is made inapproximately 40 of rotation from N to O, thereby completing the cycleof movement.

In operation, the machine is started by throwing the belt shifter 5I4 tothe left to connect the fixed pulley to the source of power andthemachine is allowed to operate continuously. The operator places astack of tongues on the bench at the right-hand end of the machine and astack of linings on the left-hand end, then, as the gaging members t6 43rise to their gaging position, the operator quickly places a tongue andlining on each of the tables l0 and I2 against the gages. Immediatelythereafter the work clamps grip the tongue and lining, the gagesdisappear from the surfaces of the tables and the work is moved inwardlytoward the uniting rolls i8 and 20. Adhesive is applied to the lowersurface of the tongue and the tongue and lining are pressed intoengagement bythe uniting rolls I3 and 20 and delivered at the upper sideof the rolls to the transferring mechanism 314 which drags the tongueassembly up between the forming plate and the retainer bar. A'When asufiicient number of pieces have been assembled and disposed in the workholder, the operator then stops the machine and places a string orelastic band about the work and removes it as a bundle from the machine.IIhe speed of the Vmachine is such that the operator is not undulyhurried in placing the work upon the tables and gaging the same, andtherefore the work may be disposed in the proper position without toomuch care on the part of the operator. In fact, after a littleexperience an operator may become so proficient that the work may bedone almost automatically. Very few adjustments are necessary for theproper operation of the machine, the only important adjustments being toadjust the proxiinity of the pick-up roll with the applying roll, thepressure between the uniting rolls I3 and 20, and the friction betweenthe spring 488 and the parallel bars M0 of the work holding means.
